3iying, pronounced "three-eye-ying", was set up in New York by the versatile Heidi Dangelmaier. Heidi has a broad experience as an expert in the female market. Among her merits, she led Sega's first initiatives to make videogames for girls and she has worked for clients as Barbie and Metlife focused in the female audience.
3iying emerged with the idea of contributing to end with "the gap between what girls want and what the marketing community is giving them". Their communication talks to girls ranging in age from 15 to 25.
